ROOFING.

Specification of Letters Patent.

Patented May 1'7, 1910.

Application filed June 21, 1909. Serial No. 503,529.

To all whom it may concern:

Be it known that I, Fnnonmox D. Coon, a citizen of the United States, residing at lBlairsville, in the county of Indiana and State of Pennsylvania, have invented certain new and useful Improvements in Roofin and I do declare the following to be a fuIl, clear, and exact descri tion of the invention, such as will enable 0t ers skilled in the art to which it appertains to make and use the same. a

This invention relates to metal roofin and consists in providing a roofing whic will be damp-proof, and proof a amst the corrosive action of the weather an sweating in cold weather.

In the accom an-ying drawing, the figure is a longitudina section of the roofing.

In practice, the roofing is made by covering the metal 1 upon both sides with a la er, as 2, of glass or enamel in a'finely groun or liquid state, and then subjecting the same to a heat sufficient to fuse the enamel or glass in order to cause it to melt and flow evenly over the surfaces of the sheet metal,and to enter the pores thereof, whereby the enamel or glass is caused to firmly adhere to the sheet metal. The sheet metal may be corrugated and before it is coated in the manner above described it is first cleaned by sand blast or acid to remove all scale or incrustation therefrom. This vitreous coating thoroughly protects the sheet metal from rust and thereby greatly prolongs the life of To i col weather, in such places where it is subjected to vapors from-the'under side a layer of cement 3 is applied to the un er layer of enamel or glass and a thin sheet of roofing is made will be clearly understood ard against sweating of the roofing without requiring a more extended explana- 1 tion.

Various changes in the form, proportion and the minor details of construction may be resorted to without departin from the principle or sacrificing any 0 the advantages ofthis invention as defined in theappended claim.

Havin thus described and ascertained the nature 0 my invention,.what I claim as new and desire to secure by Letters-Patent, is

A roofing consisting of sheet metal havin both sides covered with'a vitreous layer 0 enamel or glass, 2. la er of cement applied to one la er of the vitreous material and a layer of exible material applied to the layer of cement. h

- In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
